Flexible belt movable hood

ABSTRACT

A gas collecting main, extruding coextensively of a coke oven battery, has a flexible, heat-resistant web closing one side. An apparatus that is mounted to, or that is movable synchronously with, a coke guide cooperates with the flexible web to provide an opening in the collecting main wherever the apparatus stops so that gases, emitted from a coking chamber when the doors are removed and while pushing coke, are directed into the collecting main only through such opening.

3 Sheets-Sheet 5 FLEXIBLE BELT MOVABLE HOOD BACKGROUND OF THE INVENTIONThis invention relates to coke ovens and, more particularly, to methodand apparatus for tapping a suction main into which gases, emitted fromthe coke oven when doors are removed and coke is pushed, are directedand thereby removed from the coke oven battery.

During the pushing of hot coke from a coking chamber of a coke ovenbattery there evol-ves a large volume of gases containing dust and otherparticulate matter that pollute the air since these pollutant gases arenot now collected and scrubbed. However, because of the passage andenforcement of more rigid code requirements on air pollution, ways andmeans are being found to curb the pollution of the environmental airaround a coke oven battery. One novel apparatus that is adapted forcollecting the pollutant gases evolving during pushing of coke from acoke o-ven chamber is described hereinafter.

SUMMARY OF THE INVENTION and smoke to flow into the second conduit; suchmeans also replaces the flexible belting as the third conduit moves.

BRIEF DESCRIPTION OF THE DRAWING The drawing illustrates one embodimentof the invention wherein:

FIG. I is a schematic elevational view of apparatus in accordance withthe invention;

FIG. 2 is a view along line IIII of FIG. 1;

FIG. 3 is a schematic view ofa portion ofa coke oven showing therelation of the apparatus of FIGS. 1 and 2 thereto.

DETAILED DESCRIPTION Referring to FIG. I, an elongate gas collectingmain I 11 is fixed in a suitable location and is coextensive with thelength ofa coke oven battery 12. The gas collecting main II has agenerally rectangular shape, as shown in FIG. 2, being comprised ofparallel vertical spaced apart side walls 13, I and a flat horizontalbottom 17 connecting the side walls 13, 15. The top of the collectingmain II is open between the toes of oppositely 0pposed angles 19, 21mounted securely to the top edges of respective side walls 13, 15.

At regularly spaced apart intervals along the length of the gascollecting main 11, there are transversely extending Tee members 23which are connected suitably, as by welding, to the angles 19, 21. Thus,there are-a plurality of substantially rectangular shaped openings 25.in the top of the gas collecting main 11 through which gases passentering the main.

Outwardly extending angles 27, 29 are fitted to the side walls 13, 15respectively, as shown in FIG. 2, and these angles are coextensive withthe length of the gas collecting main 11. The angle 27 carries aninverted angle 31 welded thereto, as shown in FIG. 2, which angle 31forms a track that coacts with a pair of notched or grooved rollers 33,35.

The rollers 33, 35 are journaled respectively in a hood structure 37mounted for movement along the length of the gas collecting main 11.

The hood structure 37 comprises a vertical front wall 39 that isgenerally triangular in shape with its apex at the top and an envelope41 which is secured to the two sloping edges of the triangular verticalwall 39. The envelope 41 connects to a duct 43 which is shaped about asshown in FIG. 2 and which is connected to a gas conduit 45 by means of aflexible joint 47 of the bellows type. The gas conduit 45 is secured toandcommunicates with a hood enveloping the coke guide. Internally, thereis a butterfly type of damper 49 in the gas conduit 45 about where shownin FIG. 2.

It will be noted that one wall of the duct is journaled to the left handends of the rollers 33, 35.

Within the envelope 41 there is another vertical wall 51 that isparallel to the vertical front wall 39, but the interior wall 51 has alarge generally triangular opening 53 in it through which gases risingin the gas conduit 45 pass.

The spaced apart vertical walls 39, 51 are interconnected by a pluralityof transversely extruding Tee bars or members 55; three Tee bars 55being on the left and three Tee bars being on the right of the verticalcenterline of the front wall 39, as may be noticed by reference to FIG.1.

At the apex of the front wall 39 and the interior wall 51 there isjournaled in each wall respectively another horizontally extendingroller 57.

A flat flexible belt 59, which may be made of any suitable material suchas asbestos wire woven belting having a silicon coating, extends acrossthe top of the open gas collecting main 11, and it extends from a deadend connection (not shown) at the right hand end of the gas collectingmain 11, to the roller 35. The belting 59 passes under roller 35 and upon the surface provided by a pair of oppositely positioned angles 61, 63mounted to the front wall 39 and to interior wall 51. The belting 59 isalso supported transversely by the several Tee bar members 23 and 55.

The belting 59 passes over the upper roller 57 and down the oppositeside on the surface of the angles 61, 63 and Tee bar members 53 to theroller 33. The belting passes under the roller 33 and then lies flat onthe top ofthe gas collecting main I I Thus, the lower parallel rollers33, 35 are in upper surface contact with the belting 59 and the uppersingle and connecting rods fixed to structure adjacent the gascollecting main' 11. Thus, the belting 59 is maintained continuallyunder tension.

ovenbattery 12, to' a movable closed coke guide 91 and to a closedquenching car 93 that is moved by a locomotive 95. It will be noted thatthe collecting main ll is independently supported on structural columns97in such a way that the collecting main 11 is closely adjacent themovable coke guide 91. The coke guide 91, of course, moves relative tothe fixed collecting main 11,

In operation, the motor 77 is .activated so that the roller 33 turnseither clockwise (in FIG. 1) to move the apparatus toward the right whenthe coke guide (gas conduit 45 being fixed to' and movable with the cokeguide) moves toward the right to the next oven that is to be pushed.Whenthe coke guide is moved into position to receive pushed coke,linkage connected to the coke guide also pivots the butterfly valve 49about its support shaft 85 to the open position, where shown by dottedoutline.

lt will be observed that when the apparatus moves with the coke guide,the belting material remains stationary lengthwise, but that the rollers33, 35, 65 rotate and move respectively over, over, and under thebelting at all times. Thus, the belting provides a unique seal on thecollecting main that is easily and readily opened, at selectedlocations, in fact at any location at which the coke guide stops.

It should be recognized by those skilled in the art that in someapplications, the apparatus may not be driven by .the motor, chain andsprockets described previously, but the apparatus may just move with thecoke guide whenever the guide moves along the coke oven battery.

A feature of the invention is that the collecting main remains sealedatall times except at a location where the apparatus is positioned andthat position is at a coking chamber that is to be or is being pushed.

A feature of the inventionis that thecollecting main opens automaticallyat the coke oven to be pushed and seals automatically after pushing whenthe coke guide and the apparatus move to the next oven to be pushed.
